A student draws a geometric shape where all of the sides are different lengths. which of the following geometric shapes could the student have drawn?
a. rhombus
Consider for a moment building a tree with all possible choices. The first row would contain 8 books (each possible choice for the first book). Then, the second row would contain 7 books for each book in the first row (the choices possible for the second book). Otherwise, it would be 8*7. Following this principal, we continue to multiply down to 1. 8*7*6*5*4*3*2*1. This is also known as 8!, a factorial.
Finally, 8! = 40,320
Answer:
x=30 cm
y=24 cm
Step-by-step explanation:
y=24 cm
x=√(24²+18²)=√[6²(4²+3²)]=6√(16+9)=6√25=6×5=30 cm
T-2(3-2t)=2t+9
t-6+4t=2t+9
5t-6=2t+9
5t-2t=9+6
3t=15
t=15/3
t=5
